3DPrintCAD - online 3D design tool for 3D printing
3DPrintCAD is a 3D modeling app that runs in your browser. Build models from boxes, cylinders, spheres and other shapes, add 3D text (even wrapped around curved surfaces), cut holes, and combine parts. Import STL files to resize, rotate, split, repair hollow or broken meshes, and cut out or reshape areas. Prepare for printing with lay-flat, overhang detection and automatic supports, then export a print-ready STL for Bambu Studio, OrcaSlicer, PrusaSlicer or Cura.

Designed for your computer
3DPrintCAD is a full 3D design studio for 3D printing. Precise modelling needs a mouse, a keyboard and a large screen, so it runs on desktop and laptop computers.
